My concept for this jam is: Bubble Jail
Multiple people have been put into jails by an Evil Guy who wanted to make a challenge for you, and they were put into bubbles for cells, you have to complete a course to liberate every prisoner in that jail, and you go to the next jail, liberate the people in there, and so on until all jails are emptied of prisoners, and you fight the Evil Guy, and the prisoners live happily ever after as free men!
What do you think? Do you think it might have SOME relation to the theme?
